We thawing.

The invention described herein may be used by the Government, or any of its ofiicers or employees in prosecution of work for the Government, or by any other person in the United States, without payment to me of any royalty thereon, in accordance with the act of March 3, 1883.

The subject of this invention is an explosive.

The main object of the invention is the provision of an explosive which may be used alone or in mixture with substances which are commonly used in high explosive mixtures and which is useful in boosters, reinforced detonators, detonating fuses, primer caps and as a high explosive.

The invention consists specifically of a new explosive substance, namely, trinitrophenylbutylnitramine.

'llhinitrophenylbutylnitramine, the butyl analogue of tetryl, is a new substance not heretofore described in the published literature of chemistry. lit may be prepared by the nitration of butylaniline or by condensing butylamine'with dinitrochlorbenzene to form dinitrobutylaniline and the subsequent nitration ofv-this material.

Since theprocesses by which it may be prepared are processes which would readily suggest themselves to anyone familiar with the art I do not wish to claim any particular process for its preparation.

Pure trinitrophenylbutylnitramine crystallizes from alcohol in lemon yellow plates which melt at 97.5 to 98.0 C. It is readily soluble in benzene, ethyl ether, alcohol and acetone and is insoluble in petroleum naphtha. It contains 21.3% of nitrogen. It is a brisant high explosive, suitable for use in boosters, reinforced detonators, detonat- Application filed March 8, 1924. Serial tlo. 697,951.

ing fuses, primer caps, and as a high explosive alone or in mixture with other substances such as are usual for the purpose'as, for example, trinitrotoluene, tetryl, picric acid, etc.

0.19 gram of mercury fulminate is required for the detonation of 0.4 gram of trinitrophenylbutylnitramine. The explosive gave a figure 35.47 in the sand test, carried out according to the standard procedure of the United States Bureau of Mines, which indicates that it has a slightly greater shattering efi'ect than trinitrotoluene. It gave a drop test of 12 inches, about the same as tetryl, and itstemperature of spontaneous explosionwas found to be 210 C.

The substance forming the subject matter of this invention is, specifically, 2, 4t, 6 trinitro-normal-butyl nitramine, commonly written 2, 4, 6-trinitr0-n-butyl nitramine, which substance is entirely distinct from the iso-butyl derivative and is not to be confused therewith. The structural formula for this substance is as follows:

No I NOI I claim:

1. An explosive composition having as one of its elements trinitrophenylnormalbutylnitramine. K

2. As an explosive, trinitrophenylbutylnormalnitramine.
